IDog

iDog is an electronic robotic toy. It was first released in 2005 by Sega Toys. iDog dances to music it hears, and the LED lights change color according to the music's mood. It can also be plugged into a music player, such as an MP3 player, and the music will come through its own speakers.

iDog is the first animal to be released in the "World of iDog" line. The other animal variants were released in 2006-2008, and include iCat, iFish, iCy (also known as iPenguin), and iTurtle.

In 2007, Tiger Electronics released the iDog Amp'd. It was a version of the iDog that was upgraded, and it could nod its head and tap its foot in time with the music being played.

Classic (Hasbro)
Wave 1 in 2005 consisted of White, Black, and Fuschia. Wave 2 came out as well within 2005, including updated programming, and re-released White, Black, and Fuschia colors, with new Blue and Green. They all came with paw pads on the bottom of their feet, unlike Japan's Sega release.

Japan release (Sega)
Sega released iDogs in Japan in 2005 before the Hasbro release. Their battery compartments were in their bellies. The volume speaker on their backs looks like the LED face symbol. Compared to the Hasbro release, they lacked pawpads, lacked back legs, had slightly smaller heads, and smaller arm joints. They had two head buttons instead of the light sensor, and a microphone on the right leg instead of under the chin. Additionally, The face light pattern is different. "Happy" and "Lovely" are possible Toys'R'Us exclusives.

iDog Pup (2005)
The iDog Pup was released in both 2005 and 2007 by Hasbro. It lacks an audio input jack, instead opting for a microphone to "listen" to sounds around it to dance to.

iDog Mini (2005)
The iDog Mini was released in Japan in 2005 and 2006 by Sega. The differences between iDog Pup and iDog Mini are very small. Their outward appearances are identical, however the iDog Pup has a "Try Me" switch on its underside. Their packaging boxes are also different.

There may have only been a Pink, Blue, Black and White release of the Sega iDog Mini.

iCat (2006)
The iCat LEDs are not diffused. It has touch capability; a LED light on the face would light up when touched. It has a curved tail, cat claws, and whisker patterns on the face. Initial concept art shows the iCat being called "iKitty"

iFish (2006)
The iFish has LEDs on either side of its face. The tail would move side to side, and it could spin around in a 360 degrees motion. The spinning is an issue because of the plugged-in iPod cable getting tangled when it spins. The fins are buttons.

iCy (2006)
The iCy is a penguin. It moves side to side and can wiggle its fins. The LEDs are on the belly.

iTurtle (2009)
The iTurtle came out much later than its other animal companions. It moves its head side to side and can lift its shell up and down. The LEDs are on the shell.
